This invention relates in general to a remotely adjust

for example, from an accident.

for effecting the remote control of said adjustable mirror

operator’s compartment, it frequently obstructs the view
of the operator and, moreover, its use is often limited by
parts of, or other occupants within, said vehicle. Here
tofore, it has been necessary to tolerate these inconven
iences in order to have the re?ective member within the
reach of the operator for the purpose of adjustment.
‘Where the adjustable re?ective member of existing rear~
view mirrors is placed outside of the operator’s compart
ment, adjustment often requires the services of a second
person who moves the re?ective member according to
the operator’s instructions.
Many attempts have been made to provide a mecha
nism for remotely adjusting a rearview mirror, but none 35
have met with commercial success, insofar as it can be
determined, prior to the recent developments made by,
and in behalf of, the assignee of this application. The
apparent lack of acceptance is believed to be due pri
marily to the complex nature of the remote controlling
mechanism in previously known remotely adjustable mir
rors.
Because of the complex nature of such mecha
nisms, the mirror assemblies have been costly, difhcult
to install, dii?cult to maintain, and have often required
custom construction for a particular installation.
In a continuing effort to advance the improvement and
development of remotely adjustable, rearview mirror as

centrally disposed, threaded opening 213 extends up
wardly into the ?ange 2% from the recess 2% for threaded
reception of a screw 214, the head of which is received
into the recess 299.
The front wall 1.89 (FIGURES l3 and 13A), which is
separable from the remainder of the body member 188
in this particular embodiment, is secured to the side walls
193 and 194 by a pair of integral projections 216 which
extend from the front edges of the side walls 193 and 194
for reception into openings 217 in the front wall 139. 60
The outer ends of said projections 216 are swedged,
clinched, or otherwise upset to prevent disconnection
thereof from the front wall 189.
Said front wall 139 (FIGURE 13) has near its lower
edge a pair of frontwardly extending bosses 218 and 219
containing frontwardly opening casing recesses 222 and
223 (FIGURES 13A and 13, respectively) into which the
ends of the cable casings 224 and 226 are snugly and
slidably received. The bosses 218 and 21‘) have cable
slots 227 and 2218 (FIGURE 13) in their lower edges
which also extend through the adjacent lower edges of
the front wall 139 and communicate with the casing re
cesses 222 and 223, respectively. The control elements
186 and 187, which are snugly but slidably disposed with
control elements 18:’; and 187 to a tensioning force and
will subject the casings 224 and 226 to a compressive
force. The casings and control elements are made from
materials which can receive such forces thereon without
material, if any, change in the length of the elements and
the casings. The friction between the cable casings and
the control elements, which is augmented by the com-v
pressive and tensioning forces, will tend strongly to hold
the lever 197 and the apparatus which it is operating in
any selected position into which said lever is moved and
the spring 233 will not alter such position.
The casing 54 (FIGURE 1) and the casings 123 and
12d (FEGURE 5) serve as reaction members, the former
being under lengthwise tension and the latter under length
wise compression. Under some circumstances, the reac
tion member could be in the form of a stiff, but ?exible,
wire and the control elements could be a pair of telescoped
tubes slidably sleeved upon said wire.
It will be apparent from the variety of different control
devices disclosed herein, that other variations in con
struction will be suggested within the fundamental con
cept of the invention. Accordingly, although particular
preferred embodiments of the invention have been dis
